This one's bigger than
the single pass converted 5KTQ intercooler I used previously.
The core's 18"X7"X3", with 2.5"inlet &
outlet. I used 2.5" steel pipes with mandrel bends to
connect. The bends were 6" radius, I had to use what
I had laying around (I would have much preferred to use 3"
or 4" radius bends). On the turbo to intercooler pipe
I made on end reduce down to 2".
